change in greeks?

Am I noticing a change in the Greeks here at UMD? Recently in the past couple of years, several fraternities and sororities have either been licked off campus or fallen in tiers because of bad behavior. We now have some new sororities rising in the ranks, but instead of the snotty, bad girl reputation, these rising sororities seem to have good reputations and character. No attitude, no drama, but friendly, fun, involved in campus life. Service, sisterhood and academics are stressed. Could it be that we have a new rating system? That top tier may mean top character and the "bad girl" sorority will be on a level of their own? One can only hope.
